T o all 'whom z't may concern Be it known that I, EUGENE ROBERTS, citizen of the United States, and resident of Salt Lake City, county of Salt Lake, State of Utah, have invented certain new and useful Improvements in Spray-Nozzles for lashing Sugar and the like, of which'the following is a specilication.

' This invention relates to a device for washing sugar and the like where it is desired to direct a fine and carefully regulated spray of liquid against the material to be washed.

In washing sugar in centrifugal machines with a hand hose, such as has been commonly employed, there is an absence of means for properly distributing the spray according to the form of the wall of sugar built-up inside of the centrifugal basket or according to the nature of the sugar to be washed. As the sugar wall is ordinarily thicker toward the` bottom of the basket than at the middle and top portion, there should logically be a larger amount of liquid. sprayed against the bottom portion than the thin middle portion; moreover, at the eX- treme top of the wall, owing to the overlianging cap of the basket and the fact that there is no drip from above, the amount of ters Patent filed by Angus H. Gibson and myself, May 20, 1913 and numbered serially 768,767. It comprises essentially a valve chamber or passage provided with an inlet opening and with a series of fine jet perforations formed in the side wall of the chamber and arotatable valve plug provided with a transverse passage, the valve being so formed as to not only close and uncover the jet orifices, but also to cut off a larger number of jet orifices at the top Vthan at the bot-tom, so that an increasingly large amount of liquid will be sprayed against those portions of the sugar wall that require the largest quantity of liquid for proper' washing.

In general the invention comprises a valve chamber provided with a plurality of spray or jet orifices provided `with a transverse port, one of whose cut off edges is diagonal to the axial plane ofthe valve plug in order to cut off successively the jet orilices in one portion of the lspray plate in advance of its cutting off the orifices in other portions'of the spray plate. Y

In the accompanying drawings I have illustrated the preferred form of embodying the principles of this Yinvention in which- Y Figure l is an elevation in central section showing the valve plug seated o-peratively in the valve chamber; Fig. 2 is a Y number of line jet orifices which are preferably arranged in a number of substantially parallel vertical rows and bored on radiating lines in a Vvertical plane so as to de# liver a fan-shaped spray.

Inside of the valve chamber is mounted the valve plug c, which is preferably hollow or in the form of a'shell, provided Vat its rear with inlet openings or ports c which Vpreferably extend through a muchY larger' arcV of the circumference than does the Voutlet port at o2, in order that there may be, even when thevvalve is partially closed, an excess supply of Vliquid so as to maintain a constant pressure through the jet o riiicesVv whether all or only a few of the orifices be uncovered or open. The upper reduced portion of the valve plug c3 projects outside a washer c4 andris engaged by a clamping or tightening nut c5. i. A polygonal head c6 is formed to be engaged by a wrench to perlof the valve chamber and is surrounded byV lits V mit the partial rotation of the valve plug to adjust it properly in the valve chamber. The valve plug or shell is closed at its lowerV end, as indicated at c7. The outlet port c2 of the valve plug is formed so as to regulate the distribution of the liquid over the wall oi' sugar to be washed by narrowing the i'anshaped spray at those portions where less liquid is required to secure uniform results in the washing. One edge of the port, therefore, as shown at cw, is diagonal to the plane passing through the .vertical axis of the plug, so that the width of the opening gradually increases from the top portion toward the bottom portion. At the extreme top, however, since it is usually desirable to have somewhat more liquid at this point` the port is extended through a larger arc of the plug, as shown at o9 but with this exception, the width of the port increases from top to bottom. By making the other edge 08 of the outlet port of the plug parallel to the plane of the axis of the plug it is possible when turning the plug in a clockwise direction, according to Fig. 2, to cutoff successively the vertical rows of perforations from top to bottom, so as to secure a dis charge through the upper and lower portions of the spray plate. On the other hand if the plug is rot-ated in a contra-clockwise direction, the perforations in the first two or three rows, at a short distance below the top of the spray plate, will be closed or cut oli1 before any of the perforations in the lower part ot the spray plate are closed. As the plug is removed a new plug having a dilierent shaped port may be substituted. but generally speaking a plug formed as is the plug shown in the drawings, with one side straight and the other inclined, but with a slightly greater width at the extreme top portion will serve all practical purposes in ordinary sugar washing and permit the accurate regulation and adjustment of the spray, according to the particular requirements of the sugar being treated.

Vilhat l claim is:

l. A spray-regulating device for washing sugar and the like, embracing in its construction a conical valve casing open at both ends and having a lateral inlet opening and a series of spray orifices arranged on the opposite side of said inlet, a hollow' conical valve plug fitted to the interior wall of said casing and having closed ends prevent`- ing the end-wise escape of fluid from the casing, said hollow plug being provided with oppositely disposed inlet and outlet openings, one edge of said outlet opening being formed to leave uncovered a greater number of spray orilices at the bottom than at the upper portion in order to distribute the spray more copiously toward the bottom than at the upper portion, substantially as described.

2. A device of the class described embracing in its construction a valve casing provided at one side with an inlet opening and provided on the opposite side with a series of vertical rows of divergent jet orifices, a hollow valve plug tted into said casing and provided with an inlet opening on one side tom or" the series in order to distribute the spray unequally upon different portions of the sugar wall.

3. The combination of the valve casing provided with an inlet opening on one side and with a series of jet orifices arranged in vertical rows on the opposite side, a hollow rotatable valve provided with an inlet opening on one side and an outlet opening whose edge is formed to give it an irregular contour with relation to the series of jet orifices whereby the valve in adjusted position will leave uncovered a. greater or less area of perforations at different heights in the valve casing in order to secure the desired distri bution of the spray, substantially as described.

In wit-ness whereof, l have subscribed the above specification.
